Elevated to main event status is the original 10-round co-feature being contested for the vacant USBA featherweight title, matching former USBA champion Daniel "Twitch" Franco (15-1-3, 10 KOs), who fights out of Rancho Cucamonga, California, and Utah favorite Jose Haro (13-1-1, 7 KOs).

The 25-year-old Franco (15-1-3, 10 KOs), who fights under the Roc Nation Sports banner, was a standout amateur boxer captured the vacant USBA featherweight title last November, knocking out previously unbeaten Derrick Murray (13-0-1) in four rounds.

He lost the belt in his following fight, stopped by veteran Christopher Martin (29-8-3) in the third round of their non-title fight in Los Angeles on March 23. Franco is currently rated No. 5 by the USBA and No. 11 by the NABO.

Haro (13-1-1, 7 KOs), USBA No. 14-rated, is an all-action fighter with tremendous potential. The 29-year-old is presently riding a six-fight win streak with five victories and one draw. His lone loss as a professional was to highly-touted prospect Toka Kahn Clary (11-0) by way of a six-round decision in 2014.

The new 10-round co-feature will be an exciting match-up between Wang and Rojas (14-3, 4 KOs). Last January in China, Zhimin defeated Aekkawee Kaewmanee (16-6), by way of a 10-round unanimous decision for the vacant WBO Oriental crown.

The only blemish on Zhimin's otherwise perfect pro record is a 10-round loss by decision last September, to then 12-0 Russian prospect Ivan Baranchyk in Oklahoma.

"I honestly felt that Haro vs. Franco was a legitimate main event fight as the co-feature," promoter John Andersen. "Injuries are an unfortunate part of boxing and we're disappointed to lose a world-class fighter like Hooker. Now, though, Haro-Franco gets top billing and we're fortunate to have a solid co-feature added to a very competitive, entertaining card."
